An explainer on A320 door and escape slide indications, door opening from outside, cargo door operation and slide raft numbers on IndiGo aircraft.

These notes cover the cabin and cargo doors of the Airbus A320, written as questions and answers for crews and engineers. If anything here conflicts with your FCOM, the FCOM wins.
Door and slide indications
On the ECAM DOOR/OXY page, the word SLIDE appears in white when a door's escape slide is armed. Each passenger door also has a warning light that shows whether the slide is armed or disarmed. The white SLIDE ARMED warning light on the door comes on if the control handle is operated while the slide is armed.
The same page shows whether a door is open. The door symbol is green when the door is closed and locked. It is amber when the door is not locked, and the DOOR indication turns amber too.
The CABIN PRESSURE warning light on a passenger door comes on when both engines are stopped, the slides are disarmed and the cabin differential pressure is above 2.5 hPa.
Opening doors
Cabin doors work from inside and from outside. If a door is closed and armed and someone opens it from outside, that disarms the door and its escape slide, so the slide does not deploy.
The cargo doors use the yellow hydraulic system. If the yellow electric pump fails, crew can still pressurise the system with a hand pump on the hydraulic maintenance panel, so the cargo doors can still be operated.
Slide rafts
Each IndiGo aircraft in the original notes carried four single lane slide rafts and two dual lane slide rafts.
Part of the A320 systems series. See also Airbus Tech. Your FCOM is always the final reference.
